Research suggests that seniors with amyotrophic lateral sclerosis (ALS), like those receiving Alzheimer's care, might have developed the disease as a consequence of the behavior of their proteins.

Scientists at Lund University in Sweden have images of proteins changing shape and becoming structures that could be responsible for the neurological disease, ALS. When two proteins stick together, they can form the cornerstone of the larger structures that some experts think underlie ALS.

The researchers hope that with this knowledge of protein behavior, creating drugs to fight the condition could become a possibility.

The Mayo Clinic says about two people per 100,000 suffer from ALS worldwide. Proteins might be behind neurological disease in older persons Five to 10 percent of sufferers inherited the disease, and doctors have not found evidence why some people are more likely to develop the sickness than others.

The clinic says that ALS often begins with muscle twitching and weakness. Slurring of speech is also an initial sign of the disease. ALS eventually prevents sufferers from moving and can also affect their ability to eat, speak and breath. Unfortunately, the disease is currently incurable.

New information regarding eldercare for seniors with coronary artery disease Thursday, November 19, 2009
Research recently conducted in Maryland involving over 100 elderly men and women could have an impact on the eldercare that seniors with coronary artery disease receive.

In Baltimore, 145 men and women over the age of 65 with atherosclerosis were tested by experts from Johns Hopkins to see if dual niacin-statin therapy was more effective than traditional cholesterol-lowering therapy. Some doctors believe that niacin, often referred to as vitamin B3, can add benefit in correcting arterial narrowing when combined with statins, which are the drugs used in conventional cholesterol treatment.

"Our recommendation to physicians is that current national treatment guidelines, which recommend mainly statin therapy tailored to the severity of atherosclerosis for preventing arteries from reclogging and narrowing, appear to be sufficient and accurate for physicians and patients to follow," said Dr Joao Lima of Johns Hopkins.

Heart research could affect eldercare Tuesday, November 17, 2009
Research presented at the Amercian Heart Association's Scientific Sessions 2009 event could help prevent both younger and older persons from suffering brain damage during cardiac arrest.

When a person experiences a sudden loss in heart function, it might be possible to protect them from brain damage by quickly cooling their body.

"We now have a method that is safe and can be started within minutes of cardiac arrest to minimize damage during this very critical period," said Dr Maaret Castren, the lead author of the study.

The researchers examined 200 adult patients who went into cardiac arrest.
